Benefits

Connect a CXP-12 camera to a Coaxlink QSFP+ frame grabber The Coaxlink CXP-12 to QSFP+ Converter allows connecting a CXP-12 camera to a Coaxlink QSFP+ frame grabber using fiber optics. With multi-mode fibers, the maximum cable length can reach 150 meters. With single-mode fibers, the maximum cable length can reach 40 kilometers.

What is CoaXPress-over-Fiber?

CoaXPress-over-Fiber is a light but significant extension of the existing CoaXPress specification to support transport over fiber optics.

CoaXPress (CXP) is the de-facto standard for high-bandwidth computer vision applications. CoaXPress 2.0. the latest version of the specification, specifies the CXP-12 speed, a 12.5 Gbps (Gigabit per second) link over a coaxial copper cable.

As link aggregation is common with CoaXPress, bandwidths of 5.000 MB/s (1.250 MB/s x 4) are easily achievable with four CXP-12 links. The CoaXPress specification is hosted by the JIIA (Japan Industrial Imaging Association).

CoaXPress-over-Fiber has been designed as an add-on to the CoaXPress 2.0 specification. It provides a way to run the CoaXPress protocol, as it is, unmodified, over a standard Ethernet connection, including fiber optics. As such, CoaXPressover-Fiber uses standard electronics, connectors and cables designed for Ethernet, but the protocol is CoaXPress, not Ethernet, not GigE Vision.

What are the pros and cons of using fiber optics?

Pros

• First and foremost, cable length is not an issue anymore as fiber connectivity is basically not limited in length.

• Fiber optics provide more bandwidth, as connectivity at 10 and 25 Gbps per fiber is standard today and widely used in data centers.

• Fiber optics are immune to electrical noise, which will be a significant advantage on the production floor and in some medical applications.

• Fiber optics are lighter and smaller in size than the equivalent copper cabling, making it appropriate for applications where this characteristic is essential, like in aircrafts or vehicles.

Cons

• There is no "power over fiber". As signals in fiber optics are transmitted using light, there is no way to transfer power over fiber optics and devices such as cameras must be powered separately.

What are the cable options for CoaXPress-over-Fiber?

One of the most important benefits of CoaXPress-over-Fiber is the wide variety of connectivity options already available from multiple companies. The initial connectivity options for CoaXPress-over-Fiber and the Coaxlink QSFP+ at 10 Gbps are SFP+ and QSFP+ (Quad, or four times SFP+) modules.

The advantage of using modules compared to fixed interfaces is that ports can be equipped with any suitable type of transceiver as required by the application. A variety of transmitter and receiver types is available, allowing users to select the appropriate transceiver to provide the required optical reach over multi-mode or single-mode fiber.

What are the benefits of using CoaXPress-over-Fiber for my application?

• Ultra-high data and frame rates

• Many accessory and cabling options to cover any length requirement

• Low CPU overhead, low latency, low jitter image acquisition

• Highest camera count per PC performance

• Very competitive cost/performance ratio

• Wide industry acceptance due to JIIA and IEEE standardization

What are the jitter and latency of CoaXPress-over-Fiber? How do they compare to "traditional" CoaXPress?

CoaXPress-over-Fiber is based on the CoaXPress protocol and it exhibits the same high performance as CoaXPress in terms of jitter and latency. In addition, as CoaXPress-over-Fiber supports higher transmission speed compared to CoaXPress, the jitter and latency will be further improved in these versions.
